Answer:
Sulfur Nitride
Answer:
The type of solar radiation that is the most powerful is the Ultraviolet Radiation.
Explanation:
Ultraviolet Radiation is the radiation that has the shortest wavelength (360 nanometers), which carries a lot of energy and interferes with molecular bonds. Especially those less than 300 nanometers, which can alter DNA molecules, very important for life. These waves are absorbed by the upper part of the atmosphere, especially by the ozone layer.
The damage that ultraviolet rays can cause to humans include effects on the skin such as irritation, wrinkles, loss of elasticity, spots and cancer; also possible conditions at the ocular level and can trigger systemic lupus erythematosus.
The most powerful type of solar radiation is known as gamma radiation.
Gamma radiation consists of high-energy photons and is part of the electromagnetic spectrum. It has the highest frequency and shortest wavelength among the various types of solar radiation, which include gamma rays, X-rays, ultraviolet (UV) radiation, visible light, infrared (IR) radiation, and radio waves. Gamma radiation is generated by nuclear reactions, such as those occurring in the core of the Sun and in other high-energy processes in the universe. Due to its high energy, gamma radiation can penetrate deeply into matter and has the potential to cause ionization and damage to living cells.
Therefore, it is important to limit exposure to gamma radiation and take appropriate safety precautions when working with radioactive materials or in environments with high levels of gamma radiation.

b. element
c. molecule
d. compound
Answer:
A) Solution
Explanation:
A solution is not a pure substance, while elements, molecules, and compounds are examples of pure substances. The correct option is A.
The correct answer is a. solution. A solution is a mixture of two or more substances, so it is not a pure substance. Examples of solutions include saltwater and sugar water. On the other hand, elements, molecules, and compounds are all examples of pure substances. An element is a substance that cannot be broken down into simpler substances, such as gold or oxygen. A molecule is a combination of two or more atoms held together by chemical bonds, like water (H₂O) or carbon dioxide (CO₂). Lastly, a compound is a substance made up of two or more different elements chemically bonded together, like table salt (NaCl) or water (H₂O).

Answer: 484.94 K
Explanation:
T2 = T1 X V2 / V1
Temperature must be in kelvin so 543 + 273.15 =816.15
816.15 X 51.1 / 86
Answer: We can use the combined gas law to solve this problem:
(P₁V₁/T₁) = (P₂V₂/T₂)
where P is pressure, V is volume, and T is temperature in Kelvin.
We know that P₁ = P₂ (the pressure is assumed to be constant), and we are given V₁, T₁, and V₂. We can solve for T₂:
(P₁V₁/T₁) = (P₂V₂/T₂)
T₂ = (P₂V₂/T₁) * (T₁/P₁V₁)
We need to convert the initial temperature from Celsius to Kelvin:
T₁ = 543 + 273 = 816 K
Substituting the values:
T₂ = (1 atm * 86 mL / 816 K) * (51.1 mL / 1 atm * 86 mL)
T₂ = 0.0629 * 51.1 * 1000 = 3217 K
Therefore, the marshmallow would need to be heated to a temperature of 3217 K for its volume to change from 86 mL to 51.1 mL.

I got it right in edge
Answer : The correct option is,
Explanation : Given,
The value of pH of HCl = 6
As we know that,
pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.
The formula of pH is :
Now put all the given values in this formula, we get the concentration of hydrogen ion.
Therefore, the concentration of hydrogen ion is,
